Answer:
Hope this helps
Step-by-step explanation:
x = -25
<u>+25+25
</u>x + 25 = 0
<u>5(x+25) = 5(0)
</u>5x +125 = 0<u>

<u>Answer-</u>
<em>The printer used </em><em>642 digits</em><em> to print all the pages in the book.</em>
<u>Solution-</u>
There are 250 pages numbered starting from 1 to 250.
The total number of digits would be the sum of digits of all single digits from 1 to 9, all double digits number from 10 to 99, and all triple digits number from 100 to 250.
There are 9 single digit numbers from 0 to 9, 90 double digit numbers from 10 to 99, and 151 triple digit numbers from 100 to 250.
So,
Therefore, the printer used 642 digits to print all the pages in the book.
150 - 36 = 114 os remaining;
114/150 = 0,76 (as a decimal) = 76% (as a percentage);
Answer:
x=23 degrees
Step-by-step explanation:
We know that the sum of interior angles in a triangle is equal to 180 degrees, and we see that one of the angles is 67 and the other one is 90 degrees. So we can do this two ways, ones more complicated then the other that you may not of learned yet
The first way:
You simply do 180-67-90 to get 23
Second way:
We can use the exterior angle theorem to know that 67+x=90 degrees so you simplify on both sides and you get 23 again.
